THE PRIMARY BRIEF
- 01 · The primary finding
The National Weather Service in Anchorage issued a storm warning for the Pacific waters from Kiska to Attu in the Aleutian Islands on October 25, 2026, forecasting winds up to 60 knots and seas building to 23 feet by Monday, with severe conditions expected to persist through the week.
- 02 · The primary evidence
The NWS warning specifies winds reaching 60 knots and seas of 23 feet on Sunday night, 50 knots with 25-foot seas on Monday, and continued high winds and seas up to 35 feet through Friday. Earlier storms brought wind gusts above 40 mph, power outages, flight cancellations, and blizzard conditions to Western Alaska, including the Seward Peninsula and Aleutians. Coastal flood warnings are also in effect for other parts of Western Alaska due to a second low-pressure system.
- 03 · Why it matters
This storm warning indicates dangerous conditions for maritime operations and potential disruptions in a remote and exposed region, reflecting the severe weather patterns impacting Western Alaska in late October 2026.
The National Weather Service (NWS) in Anchorage, Alaska, issued a storm warning for the coastal waters from Kiska to Attu on the Pacific side of the Aleutian Islands. The warning was issued on October 25, 2026, at 2:31 PM AKDT, and is in effect until October 26 at 5:00 PM AKDT.
The forecast indicates challenging conditions for the region. On Sunday night, southerly winds are expected to increase from 35 knots to 60 knots after midnight. Seas are projected to build from 16 feet to 23 feet, with rain also anticipated. For Monday, southwest winds of 50 knots are forecast, and seas are expected to reach 25 feet. Isolated thunderstorms and rain are also possible. By Monday night, southwest winds will likely decrease from 35 knots to 25 knots after midnight, with seas around 20 feet.
Strong winds and high seas are expected to continue through the week. Winds could range from 25 to 50 knots, and seas may vary between 11 and 35 feet through Friday.
This specific warning follows a period of severe weather affecting Western Alaska. On Friday, October 23, a powerful Bering Sea storm caused power outages and flight cancellations across the region. Wind gusts exceeding 40 mph were reported off the coast, and snow fell around the Seward Peninsula. NWS meteorologist Alekya Srinivasan noted that gusts were expected to weaken into the 40 mph range and even 30s by Friday evening. A blizzard warning remains in effect for the Seward Peninsula.
Further reports indicate winds gusting up to 75 mph in the Aleutians and the Yukon-Kuskokwim Delta, leading to blizzard conditions along and north of the Seward Peninsula. Areas south of the Seward Peninsula are expected to see snow transition to rain. A second Bering Sea low-pressure system is also bringing coastal flood warnings to Hooper Bay and the Yukon Delta coast through Sunday evening, October 25. This system could elevate water levels again, preventing them from returning to normal for several days. The NWS Anchorage homepage also highlighted a "Strong Storm to Impact Southwest Alaska Monday and Tuesday," with Coastal Flood Advisories for the Kuskokwim Bay coast and elevated water levels possible for the Bristol Bay coast.
